GCG Construction completed the expansion of Port Sanibel Marina, 14341 Port Comfort Road, in Lee County. The project involved expanding the height of the marina building to 58 feet and creating a structure spanning 31,949 square feet. Port Sanibel Marina now offers an additional 147 indoor boat slips and nine indoor trailer slips. The marina received extensive dock repairs and new installations. The project included the construction of an approximately 860-foot retaining wall designed to separate the building from wetlands.
